H1 amendment pending from Sep15 and need to file H1 extension

[g_2k3]

Hello,

I filed my H1 amendment in September 2015 when I moved to a new project.
The amendment is still not processed and I am at the same location and now it is time to file the H1 extension

So what is the right approach to do that?

1. Recall Amendment and then file H1 extension in Premium with amendment for the new location where I moved in September
   1. Will doing it this way put my status in danger as the USCIS can claim that an amendment was not filed for the new location in September 2015

OR

1. Send a premium letter to get the Amendment approved in premium and then file the H1 extension for this new location

OR

1. Any other way

 

Thanks
